# The Late Eighteenth Century and the Debate over Modernity

History II · Contemporary History · https://tryals.app/learn/history-ii/the-late-eighteenth-century-and-the-debate-over-modernity

## An Argument, an Industry and a Contradiction

The Enlightenment was, first of all, a **publishing enterprise**.

The *Encyclopédie* of Diderot and d'Alembert (1751–1772) comprised **17 volumes of text and 11 of plates**.

* **Contributors:** Around 140 writers
* **Scale:** 17 text volumes and 11 plates volumes
* **Reach:** Sold by subscription across Europe

In **1784**, **Kant** defined Enlightenment as emergence from self-incurred immaturity. He made the main obstacle internal: a lack of resolve rather than a lack of knowledge.

**Jürgen Habermas** identified the rise of a **public sphere**. In coffeehouses, salons, and reading societies, private individuals gathered to debate public matters.

Rulers adopted parts of this programme under **Enlightened absolutism**:

* **Frederick** II in Prussia
* **Catherine** II in Russia
* **Joseph** II in the Habsburg lands (abolished serfdom in 1781, largely reversed by 1790)

These monarchs reformed laws and administration while retaining absolute authority.

## Contradictions and Modernity

These ideas coexisted with the **ancien régime**, a hierarchy of corporate **orders** and birth privileges.

Crucially, the era saw the height of the Atlantic slave trade. European economies profited directly from enslaved labour while intellectuals debated liberty.

This tension drives the modern **debate over modernity**:

* **Horkheimer and Adorno**: Instrumental reason leads directly to domination and totalitarianism.
* **Jonathan Israel**: Divides the movement into a radical democratic wing and a moderate compromise.
* **Global historians**: Argue that global trade, silver, and empire shaped modern change more than pure ideas.

> **Common pitfall:** Treating the Enlightenment as a single doctrine. It was an ongoing Argument among thinkers with deeply conflicting views.

## Practice questions

9 of this lesson's 15 practice questions, with answers. The full set is in the app.

### 1. Kant defined enlightenment as humanity’s emergence from a self-incurred immaturity. Why does the phrase "self-incurred" carry so much of the argument?

A. It locates the obstacle in a failure of nerve rather than in a lack of available knowledge
B. It frames intellectual emancipation as a gift bestowed directly by an enlightened monarch
C. It restricts authentic philosophical maturity to an educated and privileged scholarly elite
D. It denies that structural political censorship posed any genuine challenge to free thinking

**Answer:** A. It locates the obstacle in a failure of nerve rather than in a lack of available knowledge

**Why:** Calling the immaturity self-incurred makes the remedy an act of will — *sapere aude*, dare to know — rather than an act of instruction. It is a demand addressed to the reader, not a description of a deficit, which is why the essay reads as a summons and why Kant simultaneously accepts practical limits on what a subject may say while on duty.

### 2. What made the Encyclopédie politically consequential, beyond the content of individual articles?

A. It was commissioned and financed by the French crown
B. It treated crafts, trades and machines as knowledge worth systematic description
C. It was sold commercially by subscription across Europe despite suppression
D. It organised knowledge by survey and cross-reference rather than by received authority

**Answer:** B. It treated crafts, trades and machines as knowledge worth systematic description; C. It was sold commercially by subscription across Europe despite suppression; D. It organised knowledge by survey and cross-reference rather than by received authority

**Why:** The form was the argument. Putting glass-blowing beside metaphysics asserts that useful knowledge is knowledge; cross-referencing lets a bland article point at a subversive one; and selling by subscription created a European readership that no censor could reach at once. The crown suppressed it more than once.

### 3. Horkheimer and Adorno distinguish between liberating thought and instrumental reason that serves domination. What follows from this distinction for interpreting eighteenth-century intellectual projects?

A. They consider moderate thinkers wholly immune to state co-optation
B. They dismiss colonial commerce as irrelevant to philosophical enquiry
C. They view enlightened reform as masking new mechanisms of control
D. They identify the public sphere as an entirely radical achievement

**Answer:** C. They view enlightened reform as masking new mechanisms of control

**Why:** Treating the era as purely emancipatory misses how rationalised administration and imperial commerce reinforced control. The critique shows that systematising thought did not merely combat tradition; it also provided modern states with powerful techniques for centralising authority and managing human labour.

### 4. Complete the account of the eighteenth-century public sphere.

**Answer:** Habermas described a public **sphere** formed in coffeehouses, reading societies, journals and salons, in which private people reasoned publicly about matters previously reserved to the **state**. What made it consequential was less the opinions expressed than the existence of a **forum** in which authority could be discussed by people who held **none** of it.

**Why:** The structural claim is that a habit of public reasoning among people without office is itself a political fact, prior to any particular demand. Once the practice exists, the question of who is entitled to judge the government has already been answered in practice, whatever the law says.

### 5. The Encyclopédie appeared in volumes of text and volumes of engraved plates. How many volumes of TEXT did it contain?

**Answer:** 17

**Why:** **17** volumes of text, plus 11 of plates completed by 1772. The plates matter more than the ratio suggests: engraved depictions of workshops, tools and processes made the crafts legible to readers who would never enter them, which was itself a claim about what deserved to be recorded.

### 6. Sort each position by whether it treats the Enlightenment as the ORIGIN of a liberating modernity or offers a CRITIQUE of that view.

**Answer:**

- Enlightenment as origin: Rights, criticism and science begin in this period, Public reasoning by private persons is a political innovation
- Critique of that view: A reason aimed at control produces domination, not freedom, The same economies ran on Atlantic slavery throughout

**Why:** The three critiques attack different things — the content of reason, the geography of causation, and the moral accounting — and none of them denies that something important happened. That is why the debate is durable: it is not about whether the period mattered but about how to describe what it was.

### 7. Saint-Domingue was the world’s most profitable colony and was worked by around half a million enslaved people, in the same decades in which Enlightenment writers argued for universal rights. How should a historian handle that combination?

A. As a coincidence, since colonial trade was separate from metropolitan philosophy
B. As clear proof that Enlightenment thinkers unanimously defended racialised slavery
C. As central evidence on the era, since the same economies and people sustained both
D. As a key reason to date the Enlightenment's start after the slave trade's abolition

**Answer:** C. As central evidence on the era, since the same economies and people sustained both

**Why:** Colonial profits financed metropolitan wealth, and several prominent proponents of liberty invested in or defended slavery while others attacked it. Setting the contradiction aside as an inconsistency assumes the two worlds were separate, and they were the same world; naming it is not moralising but an accurate description of the economy the ideas grew in.

### 8. Arrange these eighteenth-century developments, earliest first.

**Answer:**

1. The first volume of the Encyclopédie appears
2. Joseph II abolishes serfdom in his hereditary lands
3. Kant publishes "What Is Enlightenment?"
4. The Encyclopédie’s final volumes of plates are completed
5. Joseph II dies and much of his programme is reversed

**Why:** The ordering is a warning about placing the plates. The Encyclopédie’s final volumes come out in 1772, before Joseph’s reforms and before Kant’s essay, so the great synthesising work of the Enlightenment precedes both its most famous definition and its most ambitious application by a decade or more.

### 9. The Encyclopédie began publication in 1751 and was completed with its final volumes of plates in 1772. Estimate how many years the project ran.

**Answer:** 21 (within ±2)

**Why:** **21 years**: a working lifetime for the editors, sustained across two suppressions, the withdrawal of the royal privilege in 1759, and d’Alembert’s resignation. That the project was finished at all is a fact about the subscription market as much as about the editors’ persistence.
